Scripts and playbooks to automate the installation, configuration and
|

management of Arch Linux VMs in qemu.
|
||||
`vmctl` is a script that automates the installation, provisioning and
|
||||
management of Arch Linux virtual machines.

## Installation
|
||||
|
||||
- Add the path to the `src` directory to your `PATH` environment variable
|
||||
- Create a symbolic link to `src/` directory to your `PATH` environment variable
|
||||
Just copy the `vmctl` script anywhere in your `PATH`, or clone the repository
|
||||
and create a symbolic link to `vmctl` in your `PATH`.
|
||||
|
||||
## Usage
|
||||
|
||||
### Install an Arch Linux virtual machine
|
||||
|
||||
The `vmctl install` command can be used to create an Arch Linux virtual machine
|
||||
on the fly, wherever you are. It does the following:
|
||||
|
||||
- It downloads the latest Arch Linux installer ISO image if none was downloaded
|
||||
or a new one is available.
|
||||
- It creates a `qemu` disk file.
|
||||
- It boots a new KVM that uses the ISO file as as CDROM and automates the
|
||||
installation of Arch Linux in the virtual machine (no user prompt required).
|
||||
- It can install extra packages and run custom post-installation provisioning scripts.

The keyring population process may currently (as of March 2022) take a long time.
|

This is a [known issue](https://www.reddit.com/r/archlinux/comments/rbjbcr/pacman_keyring_update_taking_too_long/).
|

|

As a workaround, if you want to speed up the OS installation process, you can
|

temporarily disable pacman keyring checks upon package installation by

uncommenting the relevant lines in `src/helpers/install.sh` (function:

`install_os`).
